To determine which shape has a greater area, we can calculate the area of each shape using the following formulas:

  1. Area of a parallelogram: \[ \text{Area} = \text{base} \times \text{height} \] For the parallelogram: \[ \text{Area} = 2 , \text{cm} \times 9 , \text{cm} = 18 , \text{cm}^2 \]

  2. Area of a triangle: \[ \text{Area} = \frac{1}{2} \times \text{base} \times \text{height} \] For the triangle: \[ \text{Area} = \frac{1}{2} \times 6 , \text{cm} \times 6 , \text{cm} = \frac{1}{2} \times 36 , \text{cm}^2 = 18 , \text{cm}^2 \]

Now we compare the areas:

  • Area of the parallelogram: \( 18 , \text{cm}^2 \)
  • Area of the triangle: \( 18 , \text{cm}^2 \)

Both shapes have the same area.

Thus, the correct statement is: Both shapes have the same area.
